Pretty sure I have a vacuum leak somewhere under the hood, the question is where. I've noticed that when I have inside air turned on, or flipped on as the case may be, outside air can still get into the car. Could this be the cause of the leak or is that something completely different?
 
when the engine is cold start your car, take some starting fluid and spray around all vacuum fittings, even the intake.
 
Vacuum leaks can be very tricky to track down. You need to bring it to the dealer where they hook it up to a smoke machine.
